PAM_LOG_DEBUG- Debugging messages. These messages are normally not logged unless the
global integer variable openpam_debug is set to a
non-zero value, in which case they are logged with a
syslog(3) priority of
LOG_DEBUG. PAM_LOG_VERBOSE- Information about the progress of the authentication process, or other
non-essential messages. These messages are logged with a
syslog(3) priority of
LOG_INFO. PAM_LOG_NOTICE- Messages relating to non-fatal errors. These messages are logged with a
syslog(3) priority of
LOG_NOTICE. PAM_LOG_ERROR- Messages relating to serious errors. These messages are logged with a
syslog(3) priority of
LOG_ERR.
The remaining arguments are a printf(3) format string and the corresponding arguments.

function does not modify the value of errno.
